Furthermore, an open window helps regulate core body temperature. The body naturally cools down as it prepares for sleep, and a room temperature between 60–67°F (15–19°C) is generally considered ideal. Natural ventilation allows for a gradual cooling effect that often feels more restorative than the dry, forced air of an air conditioner.

The most significant advantage of an open window is the reduction of carbon dioxide (CO2) levels. In a closed bedroom, CO2 exhaled by sleepers can accumulate quickly. Studies, including a notable 2015 study published in the journal Indoor Air , have shown that lower CO2 levels are directly linked to better sleep depth and improved cognitive performance the following morning. Fresh air circulation helps flush out indoor pollutants and stale air, creating a more oxygen-rich environment. 2022---Sleeping-with-the-window-open--is-it-healthy-
